EXECUTIVE SUMMARY
I don't have my own 486 PC. The last time I used one was in 2002. I couldn't play lots of old games on my modern PC. So I created a virtual 486 PC on my 64-bit Windows 10 Dell laptop. Now I can play any old DOS or Windows95/98 game on my Intel i5-4210U, 1.7Ghz, 8Gb RAM Dell laptop.

Here's the thing. You've got lots of CDs of old games, but you can't play them because they can't and won't run on your modern machine. Short of downloading the revived versions from Steam or GOG.com (that's is if they are there!), there is another way. PCem.

Today I figured out how to use PCem to play the old DOS and Windows flight simulators in their native environment. Woo hoo!

I'm talking high-fidelity Soundblaster sounds and music, accurate CPU cycles as per the actual PC BIOS and motherboards. I'm talking about Voodoo1 and Voodoo2 3Dfx rendering of graphics (better than what any 3Dfx software Glide Wrapper can do). In short, I can create my own virtual 486 machine with all the trimmings (devices and drivers) so that I can play classic DOS and Windows games with the authentic 1990s aural and visual experience!

PCem is a PC emulator that's been around for some time. After lots of poking around, I managed to setup up virtual machine (emulator) running on MS-DOS 6.22 bootable disk and Windows 95. The MS-DOS bootable disk is for playing DOS games - especially Tornado which needs at least 605 kilobytes of free conventional RAM. The Windows 95 mode is for running Mig Alley and other dinosaur Windows flight simulators that modern computers abhor.

Using PCem, I emulated a 486DX/2 40Mhz machine. That was expensive state of the art back in the early 1990s.

Cinemagraphs are basically animated gifs created using Videos. Cinemagraphs are still photographs in which a minor and repeated movement occurs, forming a video clip. They are published as an animated GIF or in other video formats, and can give the illusion that the viewer is watching an animation.

A Cinemagraph makes the GIF file come alive! You can select just a small portion to animate whilt the rest of the screen is static. As in the Screenshot 1.

Here's the best part of a Cinemagraph. It's file size is smaller compared to an animated GIF of the same content. Look at Screenshot 3. An animated GIF of the same countent would be at least 2 Megabytes in size. The Cinemagraph is a 10 times smaller than the animated GIF. Using a Cinemagraph on a web page would lead to faster load times of a webpage, compared to a bloated animated GIF.

Here is the link to download the Cinemagraph program (free
by Microsoft)

I just discovered how to play Digital Integration's venerable 23-year old DOS game Tornado on my iPad Air. I used iDOS 2 and the iExplore app. Check out these screenshots. The game runs well on my 2014 iPad Air. And it will also work on your beloved iPhone. Well, any device running iOS.

The problem here is no matter what opacity setting you choose for the virtual keyboard,
you can hardly make out the game's cockpit graphics because of the way the virtual
keyboard is overlaid on top of the game.

I'm still learning about E-Learning and so that makes me a learner still. Even Yoda had to be a learner. Love learning with Moodle, chess, reading war non-fiction books, married to one wife with two lovely girls.
